Johnny, engrossed in his book, hears a soft knock at his door. In walks Tina, his sexy, green-eyed step-sister, dressed in a tantalizing lingerie set that hugs her perfect, round ass and accentuates her white, athletic body. She saunters over, her long, brown hair cascading down her back, and without a word, sinks to her knees. With a sultry look, she unzips his pants, revealing his throbbing length. Tina, with her nipple piercing glinting, takes him in her mouth, her full lips wrapping around him as she begins to suck, dirty-talking all the while.
